Gallium Nitride. Gallium nitride grown by various bulk and epitaxial techniques without intentional chemical doping is almost always found to be electrically conducting due to the presence of free electrons, and the origin of that n-type conductivity in terms of the donor or donors involved has been the subject of many experimental and theoretical investigations.

Silicon has a bandgap of 1.1 eV. Wide bandgap refers to higher voltage electronic band gaps in devices, which are larger than 1 electronvolt (eV). A GaN high electron mobility transistor (HEMT) is a lateral device. Gallium nitride is a well studied electronic material and thin GaN films for electronic applications are today routinely made by CVD. In close collaboration we are trying to improve the understanding of GaN CVD to enable better fabrication of GaN films.
